STEREOTYPERS CASTING MACHINE.

Application filed November My invention relates to a stereotyperscasting machine and more particularly to a machine having a pair olspaced platens against one ot which the matriX is placed,V

" stantially horizontal and vertical portions;

and a Further object ot' my invention is the provision ot a pair ofplatens and suitable hinging and locking means theretor so arranged thatthe platens may be placed either in a substantially horizontal orvertical position by which arrangement the upper platen may be swung tothe vertical position and the lower platen to the horizontal position,the matrix and gauges placed as desired on the inner face of the lowerplaten, then the upper platen lowered onto the gauges and thc twoplatens locked together. When the platens are locked together, thematrix and gauges are firmly held in position and the two platens maythen be swung into the vertical position and molten metal poured intothe chamber thus provided andthe casting made.

A lurther object of my invention is the provision of means forconnecting the platcns to the supporting trame so arranged that saidplatens may be swung about either ot two axes, one ot said axespreferably eX- tending vertically and the other horizontally. Incarrying out this feature ot my invention l. prei'ieraliily provide ayoke pivotally connected to the trame so that it may be swung about avertical axis and to which the platens are pivotcd, the pivotalconnection between. the platens and the yoke member being so arrangedthat the platens are substantially balanced on the yoke member and,therefore, easily swung from a horizontal to a vertical position or viceversa.

.It is a further object oi my invention to provide an arrangementwhereby the distance between the platens may be conveniently varied tomake castings of different thicknesses, for example, type-high orthinplate, the latter commonly being termed 9, 1922. Serial No. 599,821.

sl-rivers, suitable gauges, ot course, being provided tor the respectivecastings.

A further object ot my invention is the provision ot a novel adjustablehinge for connecting the two platens.

A further object of my invention is the provision of novel quick-actingmeans, preferably adjustable, 'for locking the two platens together.

A further object ot my invention is the provision of a metal pottiltably mounted on the vertical frame portion in combination with meansfor heating the metal pot so that molten metal may flow directly fromthe pot into the casting chamber when the platens are swung upwardlyinto a vertical position.

The invention consists in the novel constructions, arrangements anddevices to be hereinafter described and claimed tor carrying out theabove stated objects and such other objects as will appear trom thetollewing description oit certain preferred embodiments illustrated inthe accompanying drawings, wherein- Fig. 1 is a perspective view of amachine embodying th principles of my invention, the lower platen beingin the horizontal position, and the upper platen having been swung backso that the matrix and gauge bars may be properly positioned on theinner face of the lower platen;

Fig, 2 is a perspective view of the machine, showing the platens in thevertical position so that the molten metal may be poured into thecasting chamber therebetween;

Fig. 3 is a plan view of the machine, certain portions being brokenaway, showing the lower platen in the same position as it occupies inFig. l, the upper platen, however, having been swung down into operativerelationsip with the lower platen and locked to it;

Fig. L is a sectional vView taken On the line t-fi of Fig. 3, the twoplatens, however, having been swung in a horizontal plane from theposition shown in Fig. 3 through an angle of 900;

Fig. 5 is a sectional view taken On the line 5 5 of Fig. li;

Fig. G is a side elevational view, certain parts being sectioned, of oneof the hinges preferably employed tor connecting the platens;

llt)

The two platens may be locke-d iiico-operating relationship by anydesired means, but I preier to use a pair of quick-acting, adjustablelocking devices of the construction shown in the drawings, seeparticularly Figs. 7 and S. rlhe respective platens 23 and 25 areprovided with lugs 37 and 38. Each lug 37 is provided with a slot 39 forthe insertion ot a bolt 40. Links 41 adapted to be positioned againstthe respect-ive sides of the lugs 37 and 38 are pivotally connected attheir lower ends to the lug 37 by the bolt 40. Adjacent their upper endssaid respective links are provided with peritorations 41a and 41",through which a bolt 42 may be inserted, said bolt being shown asextending through the peillorations 41a. A cam member 43 is attached tothe upper ends of said links by the bolt 42 and is adapted to engage theseat formed on the upper surface of the lug 38, said cam member having ahandle portion 43a. When the platens are in the position shown in Fig.1, the locking devices hang downwardly, out of the way, and, when theplatens are in the position shown in Fig. 3, the locking devices may beswung upwardly to bring the cam members. into engagement with the seatson the respective lugs 3S, thus locking the platens ton gether, as shownin Figs. 2 to 5, inclusive. The lugs are tapped for the insertion oitadjust-ing screws44, the inner ends ot' said screws being adapted tobear against the upper sides of the respective bolts 40.

ln Figs. 1 to 3, inclusive, type-high gauges are shown in place betweenthe two platens, and, when such. gauges are used, the bolts 33 of thehinges 26 are inserted through the apertures a of the links 35, andlikewise the bolts 42 of the locking devices 27 are inserted through theapertures 41a of the links 41. In Fig. 9 thin-plate gauges 45 are shownin position between the two platens, and, in that case, the bolts 33 ofthe hinges 26 are inserted through the apertures 35" of the links 35,and the bolts 42 of the locking devices 27 are inserted through theapertures 41" oit the links 41, thereby bringing the platens together incloser relationship. 1t will be seen, therefore, that adjustableconnections are provided between the links 35 ot the respective hinges26 and the platen 23 and also adjustable connections are providedbetween the links 41 and the cam members 43 of the respective lockingdevices. 1n order to take care of any inaccuracies in manufacture andany wear that may develop, provision is made :tor varying the distancesbetween the bolts 33 and 34 of the respective hinges and the bolts 4()and 42 et the respective locking devices, this being accomplished byturning the screws 3G of the hinges and the screws 44 of the lockingdevices. By this arrangement a very iine adjustment is obtained and theplatens may be brought into close fitting engagement against therespective sides of the gauge bars.

A metal pot 46 is positioned on brackets 47 carried by the respectivevertical :trame members 16. At each side the metal pot is provided witha pair of spaced, laterally projecting lugs which are adapted to lie insuitable recesses provided in' the bracket members 4i'. Thisarrangenient makes it inipossible to tilt the metal pot accidentally andyet permits the molten metal to flow from the pot through the spout 4Gbthereof directly into the casting chamber formed between the twoplatens. The platen 23 is provided with a portion 23a to direct themolten metal into the casting chamber. The portion 23u may be made inthe form of a handle, see Fig. 3, to facilitate handling the platens.rllhe pot and metal therein are preterably heated by suitable burners 48connected with a source of gas or gasoline.

The traine is provided with a foot-piece 49, see Figs. 2, 5 and 9, whichforms a sup.- port lor the right-hand end of the platens, havingreference to Figs. 1 and 3, when they are in the aositions showntherein. The piece 49 and the bottom of the yoke 18 prevent the platensrocking to any appreciable extent on the members 24, the piece 49 beingparticularly useful when a small casting is made in the bottom of thecasting chamber, in which case the tendency for the platens to tiltclockwise being much greater than when. full size castings are made.

I do not intend to limit my invention to the details of constructionshown and described herein, except only in so far as certain of theappended claims are specifically so limited, as it will be obvious thatvarious modifications may be made by those skilled in the art withoutdeparting from the principles of the invention.
